What ?  Is Element Acoustics selling cars now?  The answer is NO.  :)  

Some of our customers may have heard that Burmester is working with another German auto maker on their new car audio.  We couldn't say anything until the secret reveals itself.  Now, we are just happy to announce that all upcoming 2014 Mercedes Benz S class will have Burmester audio as an optional add-on.  As in the lat partnership with high end luxury cars (Porsche and Bugatti), Burmester is again broadening its impact on the high-end automobile field.
